Well I put in the new style breathers. Still blowing oil, maybe more now. One thing is that it seems it's only coming out of the rear head. Only thing I think is that the oil return in the rear head is blocked. Anyone ever encounter this?

at the suggestion of Doc and Wiz, when I dropped my cams in my 12 I decided to stay with stock pushrods so the rocker covers came off. While I was in there they both suggested that I drill out those return holes to 1/16" and the taper the holes with a 1/8" bit.

That sucks bro. Where these the axtell cyl in your sig that took a chit? Did the s&s drop right in to the cases? Reason I ask my cases are bored for axtell cylinders but want to go s&s but am told the spigots are bigger and wont fit my cases

Sorry to hear. How many miles on the build? Any thought as to root causes?

Can't be 100% sure, but I am hearing that a few others have had problems with the Axtell cylinders. I think I had about 7,000 miles, I'd have to check my records.

This problem existed when I had it tuned by Bean. I'm concerned that it may have given some false gas analyzer readings, or contributed to knock as we had to take a bunch of timing out. Maybe Bean or Georges will chime in with their opinion on this.
